Solution Overview
Problem
Software developers face challenges in migrating codebases to new frameworks or libraries, as existing tools struggle with corner cases and require lengthy manual rewrites, failing to produce compilable intermediary code effectively.
Innovation Solution
A semantic-aware and self-corrective re-architecting system using a migration tool that leverages abstract syntax trees and semantic analysis to automatically migrate software code from one framework or library to another, generating updated code while maintaining semantic correctness and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a migration tool is used to automate code migration, then productivity is improved, but the tool fails to handle corner cases and produce compilable intermediary code
Solution Approach 1:
The patent introduces an intermediary representation (IR) as a mediator between the source code and target code. The IR serves as a semantic bridge that captures the meaning and structure of the source code in a framework-agnostic form, enabling reliable translation to the target framework while handling corner cases. This intermediary layer resolves the contradiction by decoupling the migration logic from framework-specific details.
Solution Approach 2:
The migration tool performs self-correction by automatically detecting and fixing issues in the generated intermediary code. The system uses semantic analysis to identify compilation errors and corner cases, then applies corrective transformations autonomously without requiring manual intervention. This self-service capability ensures both high productivity and reliability in code migration.
2Manufacturing precision
If manual rewriting is used to ensure semantic correctness, then manufacturing precision is improved, but the process becomes time-consuming and less productive
Solution Approach 1:
The patent replaces manual mechanical rewriting with automated semantic analysis and transformation. The system uses programmatic analysis to understand code semantics, generate target code, and verify correctness automatically. This substitution maintains high semantic precision while dramatically improving migration speed and productivity.
Solution Approach 2:
The migration tool incorporates feedback loops that automatically verify the semantic correctness of generated code. The system analyzes the target code against the source code semantics, detects discrepancies, and applies corrective transformations. This feedback mechanism ensures manufacturing precision (semantic correctness) is maintained while the automation preserves productivity.
3Device complexity
If existing rudimentary tools are used, then device complexity is reduced, but the tools fail to handle corner cases and produce reliable results
Solution Approach 1:
The patent segments the migration tool into distinct functional modules: semantic analysis module, intermediary representation generator, code transformation module, and verification module. Each module handles specific aspects of the migration process, including corner cases. This segmentation maintains manageable complexity while enabling comprehensive and reliable handling of all code scenarios.

AI summary
Disclosed herein are system, method, and device embodiments for semantic-aware and self-corrective automatic re-architecting. An embodiment operates by determining abstract syntax trees based on source code and target code, determining method identifier information based on the abstract syntax tree of the source code, determining reference location information based on the abstract syntax tree of target code, generating updated source code based on the abstract syntax tree of the source code, and determining interface mapping information including a mapping between a first service method of the source code and a second service method of the updated service code. Some embodiments may further operate by validating the interface mapping information, and generating updated source code based on the method identifier information, the reference location information, the interface mapping information, and the abstract syntax tree of the source code.
